Drag Racing UFO's

While Trawling for Shrimp late one night in the Louisiana Bayou with a friend, the sky was pitch black out that night. I was on the back the boat looking into the night sky at all the stars that were visible. I suddenly looked up and saw two circle shaped objects high in the sky, they were flying as high as Commercial Aircraft fly, they were silver/white in color, with a glowing bluish all around and leaving a blue trail behind each. They were flying side by side towards the North with one just behind the other as if they were drag racing. I quickly looked at my friend to hurry up and look and just when i looked back up I just caught them going beyond the horizon. They had to be traveling 50 or more times the speed of a Commercial Jet Liner. They were flying as high as Commercial Air liners, other than the shape and color of them, thats all that I could make out, and that they were FAST.
Date is approximate.  PD
